Application filed April 27, 1905. Serial No. 267,738.

1'0 (LIZ 11172-0171, it may concern:

Be it known that I, ARTHUR HENRY GIBSON, a subject of the King of Great Britain, and a resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Fluid-Pressers, of which the following is a specification.

The object of my present invention is to provide certain improvements in the construction, form, and arrangement of the several parts of that type of fluid-presser which is used for reciprocating a tool-as, for instance, a rockdrillby columns of fluid under pressure, whereby the fluid pressure may be raised from time to time to the desired degree when it has become lowered by leakage to an undesirable extent, the device being so arranged that the presser itself may be employed for thus raising the pressure, thereby doing away with the requirement of separate or independent means for accomplishing this result.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents the presser in side ele vation in connection with a rock-drill, a por- I tion of the rock-drill being shown in section;'

and Fig. 2 is a longitudinal central section of the presser partially in side elevation with the parts in the positions which they assume when the presser is being used for moving the columns of fluid to operate the tool, the presserpiston being shown at the middle of its stroke.

The presser-cylinder is denoted by 1, its front head by 2, its back head by 3. The rock-drill cylinder is denoted by 1* and its piston by 2*. The pressercylinder is supported upon a portable base 4, in the present instance by an upright 5. The presser-piston is denoted by 6, and it is provided with a hol low trunk 7, which projects to the front and rear of the piston-head. The front projecherein shown as driven from an electric motor 13 by means of a pinion 14;, which intermeshes with agear 15. This motor is also supported on the base 4 by means of an upright 16. The crank-shaft casing is secured directly to the motor-casing and forms in the present instance an integral part of the tubular guide 9 and rear head 3 of the presser-cylinder.

An induction-valve 17 has its port 18 opening into the presser-cylinder 1 at a point midway between the limits of the stroke of the piston. This port 18 is therefore alternately opened to the opposite sides of the piston as the piston is reciprocated.

The cylinder-heads 2 and 3 of the pressercylinder are provided with ports 19 and 20, with which the fluid-pressure pipes 21 22 are connected, which pipes lead to the cylinder 1* of the rock-drill upon opposite sides of the piston 2*. In the present instance the connection of the pipe 21 with the port 19 is as follows: The pipe 21 is connected to a T-coupling 23. The mouth of the port 19 is provided with a pipe 24, which is connected to another T-coupling 25. A manually-operated cock 26 is connected to the couplings 23 and 25, the plug 27 of which cock is provided with a through-port 28, which is arranged to control direct communication from the port 19 to the pipe 21. This plug 27 is provided with the usual operating-handle 29. A branch pipe 30 connects the coupling 23 with the coupling 25 around the cook 26, in which branch pipe I locate a puppet-valve 31, ar-

..ranged to be opened by pressure from the presser-cylinder, but closed against pressure from the rock-drill cylinder.

The pipe 22 is connected to the port 20 of.

cylinder, the cock-plugs 27 and 35 are turned to close direct communication from the ends of the presser-cylinder to the pipes 21 22. As the piston 6 is reciprocated the presser will act as a compressor by alternately forcing the fluid through the puppet-valves 31 and into the pipes 21 and 22. When the pressure has been raised to the desired amount, the cock-plugs 27 and 35 may be turned to bring the opposite sides of the piston 6 in the cylinder 1 into direct open communication with the pipes 21 and 22, respectively. The reciprocation of the piston is then utilized for moving the columns of fluid to perform the work required. Whenever the pressure of fluid leaks down to an undesirable extent, it may again be raised to the desired point by repeating the operation above described.

It will be seen that when the device is being used for raising the fluid-pressure the port 18 of the induction-valve 17 of the cylinder is alternately opened to the opposite sides of the piston for supplying fluid thereto for being forced through the puppet-valves 31 and 10 into the column of fluid in the pipes 21 and 22.

What I claim is 1. The combination with a percussive toolcylinder and a piston therefor, of the cylinder of a presser, a piston therefor, pipes connect ing the two cylinders upon opposite sides of the pistons and means for permitting the use of the presser as a compressor.

2. The combination with a percussive toolcylinder and a piston therefor, of the cylinder of a presser, a piston therefor, pipes connecting the two cylinders upon opposite sides of their pistons, manually-operated cocks in the of the case in the Patent Oflice.

[SEAL] said pipes, branch pipes connecting the first named pipes upon opposite sides of their cocks and puppet-valves in the branch pipes, whereby the presser-cylinder may be used as a compressor-cylinder when so desired, to raise the pressure in the first-named pipes.

3. The combination with a percussive toolcylinder and a piston therefor, of the cylinder of a presser, a piston therefor, pipes connecting the two cylinders upon opposite sides of their pistons, manually-operated cocks in said pipes, branch pipes connecting the first-named pipes upon opposite sides of their cocks, puppet-valves in their branch pipes and an induction-valve arranged to be alternately opened to the opposite sides of the presser-piston as the piston is reciprocated.

4. A presser-cylinder, a piston therefor, a pipe leading from the cylinder upon one side of the. piston, a manually-operated cock in the pipe, a branch pipe connecting the first-named pipe upon opposite sides of the cock and a puppet-valve in said branch pipe.

5. A presser cylinder, a piston therefor pipes leading from the cylinder upon opposite sides of the piston, manually-operated cocks in said pipes, branch pipes leading around the manually-operated cocks and pup pet-valves in the said branch pipes.
